Eustachian Tube Irritation

I have spent much of my working life seeing children only in General Practice. For about 10 + years I have been especially interested in the relationship between distress in early infancy and ear problems. For some years I have been talking of the condition I call Eustachian tube Irritation [ETI], which I believe is a common cause of infant distress and is an early manifestation of ear problems in some infants. I have now seen 500 + infants presenting with distress who I believe have this condition.
